An engineer must configure neighbor discovery between the company router and an ISP. What is the next step to complete the configuration if the ISP uses a third-party router?
Answer is A
Tested on packet tracer
int g0/0
duplex full
speed 1000
lldp transmit
lldp receive
do show lldp neighbors
#LLDP is not enabled
lldp run
do show lldp neighbors - shows devices
I'm going to be that oddball, but here is the reason why. Just hear me out.
Answer A. Why even do this command when lldp Tx/Rx has already been configured.
Answer B. You may need cdp for your internal network since this is Cisco afterall: use lldp for your connection w/ the ISP, especially since they use 3rd party equipment.
Answer C. You can't touch the ISP's equipment. That is off-limits.
Answer D. I'm leaning towards this one because of the mention of 3rd party device owned by the ISP. There has to be a reason why they brought that up, otherwise why bother. The port configuration was hard-set to full and speed of 1000. Why then leave the auto-negotiation (on by default) .
Here's what Cisco has to say about GigE autonegotiation: "[It] negotiates flow control, duplex mode, and remote fault information. You must either enable or disable link negotiation on both ends of the link. Both ends of the link must be set to the same value or the link does not connect.
Ignore my previous comment. Better yet delete if please if you're a moderator. I don't want to mislead people here. I completely ignored another member testing Answer A on Packet Tracer. My fault.
Disabling and Enabling LLDP on an Interface – LLDP is disabled globally on all supported interfaces. You must enable LLDP globally to allow a device to send LLDP packets.

In my opinion, lldp transmit and recieve are configured on the port. We need LLDP to be configured globally in order to complete the company router configuration. Also the phrasing of the question (complete THE build) accompanied by the "snip" of the company router is against answer C as being the correct one.
And this is from Cisco :
"Depending on the device, LLDP may be enabled by default." so in this question, we don't know if it's already globally enabled or not.
Sorry for posting 3 messges but you can't edit. I would disable CDP on gi0/0 (answer C)
Again from Cisco : "To disable CDP on a specific interface, such as the interface facing an ISP, enter no cdp enable in the interface configuration mode."
